Indications for Use
The Merits Model E Series Lift Chairs are intended to assist elderly and/or physically challenged persons, who have difficulty rising from a seated position to a standing position.
Device Story
The Merits Model E Series Lift Chair is an electric positioning chair designed to assist individuals with mobility limitations. The device consists of an upholstered fabric chair assembly mounted on a welded steel frame. It utilizes one or two motorized linear actuators to adjust the chair's position, operated by a handheld, push-button pendant control. Powered by standard AC wall outlets, the chair is intended for use by elderly or physically challenged persons to facilitate the transition from a seated to a standing position. The device functions as a mechanical aid to improve patient independence and mobility.
Clinical Evidence
